Method Detail

add

public boolean add(int k)

Description copied from interface: IntCollection

Ensures that this collection contains the specified element (optional operation).

Specified by:

add in interface IntCollection

See Also:

Collection.add(Object)

contains

public boolean contains(int k)

Description copied from interface: IntCollection

Returns true if this collection contains the specified element.

Specified by:

contains in interface IntCollection

See Also:

Collection.contains(Object)

rem

public boolean rem(int k)

Description copied from interface: IntCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface IntCollection

See Also:

Collection.remove(Object)

size

public int size()

Specified by:

size in interface java.util.Collection<java.lang.Integer>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Collection<java.lang.Integer>

toIntArray

public int[] toIntArray()

Description copied from interface: IntCollection

Returns a primitive type array containing the items of this collection.

Specified by:

toIntArray in interface IntCollection

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray()

toArray

public java.lang.Object[] toArray()

Specified by:

toArray in interface java.util.Collection<java.lang.Integer>

toIntArray

@Deprecated
public int[] toIntArray(int[] a)

Deprecated.

Description copied from interface: IntCollection

Returns a primitive type array containing the items of this collection.

Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.

Specified by:

toIntArray in interface IntCollection

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

toArray

public int[] toArray(int[] a)

Description copied from interface: IntCollection

Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array.

Note that, contrarily to Collection.toArray(Object[]), this methods just writes all elements of this collection: no special value will be added after the last one.

Specified by:

toArray in interface IntCollection

Parameters:

a - if this array is big enough, it will be used to store this collection.

Returns:

a primitive type array containing the items of this collection.

See Also:

Collection.toArray(Object[])

addAll

public boolean addAll(IntCollection c)

Description copied from interface: IntCollection

Adds all elements of the given type-specific collection to this collection.

Specified by:

addAll in interface IntCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.addAll(Collection)

containsAll

public boolean containsAll(IntCollection c)

Description copied from interface: IntCollection

Checks whether this collection contains all elements from the given type-specific collection.

Specified by:

containsAll in interface IntCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection contains all elements of the argument.

See Also:

Collection.containsAll(Collection)

removeAll

public boolean removeAll(IntCollection c)

Description copied from interface: IntCollection

Remove from this collection all elements in the given type-specific collection.

Specified by:

removeAll in interface IntCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.removeAll(Collection)

removeIf

public boolean removeIf(java.util.function.IntPredicate filter)

Description copied from interface: IntCollection

Remove from this collection all elements which satisfy the given predicate.

Specified by:

removeIf in interface IntCollection

Parameters:

filter - a predicate which returns true for elements to be removed.

Returns:

true if any elements were removed.

See Also:

Collection.removeIf(java.util.function.Predicate)

retainAll

public boolean retainAll(IntCollection c)

Description copied from interface: IntCollection

Retains in this collection only elements from the given type-specific collection.

Specified by:

retainAll in interface IntCollection

Parameters:

c - a type-specific collection.

Returns:

true if this collection changed as a result of the call.

See Also:

Collection.retainAll(Collection)

iterator

public IntIterator iterator()

Description copied from interface: IntCollection

Returns a type-specific iterator on the elements of this collection.
